This can’t be good news for the Burger Kind social media team. About an hour ago, a tweet appeared in its Twitter stream saying, “We just got sold to McDonalds! Look for McDonalds in a hood near you,” and the avatar was changed to the McDonald’s logo.

Since then, the timeline has turned into complete mayhem, filling up with outrageous claims about Burger King food and staff, shoutouts to Chicago rapper Chief Keef, and RTs of folks freaking out over the hack.

So far, hacker group Anonymous seems to be claiming responsibility, dubbing the hack “#OPMadCow.”

The fact that it’s a national holiday may be one reason that Burger King hasn’t been able to regain control of the account yet.

UPDATE: Here’s an official statement about the incident from Burger King, via BuzzFeed:

We have worked directly with administrators to suspend the account until we are able to re-establish our legitimate site and authentic postings.
